Homework Help: Pre-calculus

Posted by Lucy on Saturday, August 23, 2008 at 2:39pm.

The angle of elevation from the end of the shadow to the top of the building is 63 degrees and the distance of 220 feet.

1) Find the height of the building to the nearest foot

2) find the length of the shadow to the nearest foot


If 0 degrees </= 360 degrees, solve the equation, sec x= -2. I do not know how to solve this and cannot find an example in my book.

Thanks for all your help!
